Using these two webmail applications one can read mail on the mail servers maintained by C&CZ (and others, like CMBI or UCI).

Configuring an email client

Default configuration choises for a mail client are:

* To read mail the preferred protocol is IMAP.
The POP protocol can still be used, but not all messages will be found.
* Using IMAP encryption via SSL or TLS is mandatory!
For POP one has to use SSL encryption!
* The server for reading email is the post.science.ru.nl.
You will need your FNWI loginname and password.
* The server for sending emails is the smtp.science.ru.nl.
You do not need a loginname or password if used from the Huygens building.
Outside the Huygens building you will need your loginname and password and
encryption via TLS is mandatory.
More info can be read at Authenticated SMTP.
* For sending email one can often choose a port number.
Choose port 587 (instead of poort 25), and messages will not be filtered!
Sending mail will be faster, but also it will be possible to attach .zip or .exe files.
Authentication is mandatory now!

Mailing lists

There are simple lists of mail addresses possible, which can be requested through Postmaster and after that maintained by the owners themselves through The Do-It-Yourself website, but there are also highly configurable and moderatable
There are mailman mailing lists, e.g. the list of FNWI-employees or the list of FNWI-students. Usually one can add oneself to or remove oneself from such a mailman mailing list. Every mailman mailing list has a moderator, who can approve or reject messages to the mailman mailing list. For mailman list admins: To filter spam one can choose in the "Privacy options..." under "Spam filters" as "Spam filter regexp:"

X-Spam-Score:.*\*\*\*\*\*

and check the radio button "Discard" and hit "Submit Your Changes" on the bottom of the web page.

Authenticated SMTP

It is possible to authenticate to the mail server with your login name and password. If you use authentication, the mail server will never refuse mail with the error "Relaying denied". So it is possible to use our mail servers from outside FNWI. Without authentication you have to use the SMTP server of your Internet provider to prevent this error. If you own a laptop, you can always use the mail servers of FNWI, both at work and at home, providing you authenticate. The configuration of authenticated smtp for several mail clients is described.
